Boost problems

[Azman]

Afternoon folks,


Just been out playing in the rain on the boost pipes to try to sort the leak out. Have managed to get the new dump valve on which has helped but seem to be getting a boost spike on gear change, so much so the hose from the cooler to the top pipe came off (mikalor clamp and all), can't figure out why.

Anyway only boosting to 0.7 bar now and rarely seeing 1bar, I have been across all the seals to make sure they are tight and all seem fine. got a spare pipe to sort the split one out so that is not a problem anymore. dump valve is new and sealed well with the strongest spring I can get in it and that seems to be holding under boost.

Any thoughts?

Ond another one to ask before I go firtling round.

Oil leak on passengers side of the engine?

Possible causes?

Oil pressure thingy (tin can one)?
Little oil pressure switch?

Can't think of anything else on that side to cause a leak?

Cheers guys.

sounds like oil switch .don't know about your boost problem though.

Oil switch, big tin can one?

Sounds like the DV is in the wrong way round or is sticking?

Dump valve is sound as a pound I think brand new piston type as the old one was shot, well greased and with a stronger spring than those that came with it so it should stay shut and I can hear it when it opens (tell tale piston whistle) and the boost comes straight back up 0.7bar again after change. Think I have it the right way round. Oriented it same as the one that came out.

Thinking things will get better hopefully when I strip the whole lot off and clean everything to fit the samco's well that is a fingers crossed moment. want to try to cure before that though.
